Depends on what you're moving on from. An ex? Friends? Last year during the summer, I broke contact with two friends I graduated middle school with because they never bothered to contact me or made an effort to be my 'friend.' I haven't made contact with them since then, and I personally feel that it has helped me move on. Why waste my energy on them when I can spend it on someone who does care?
I do admit that sometimes I did want to get back in touch, but then I remembered how little effort they gave and rejected the idea.
